Since I DIY all my juice, I don't really fear running out. I just stock up in advance and I'm good for the next year or so. As far as gear goes, I've got 2 great mechs, with plenty of spare parts to rebuild them if necessarry, and 2 dedicated rba's each, plus a couple more rba's. A ton of wick and 100ft of wire (on the way). 2 chargers ( 1 i4 intelli and 1 cheapy, though I'll upgrade that to a i2 intelli soon enough) and about 8 18650's and 4 18350's. I could use some more batts, but other than that I'm good for a long time to come.
